9. Inspection and maintenance of the heat-conducting oil heater <br>9.1 Items for daily inspection. <br>Heating body: If the terminal is overheated and damaged, check whether the heating element is damaged, and decide whether to replace or repair it according to the degree of damage. Check the sealing and sealing parts of the heating element If there is oil leakage in the weld seam with the tube plate flange, the electric heating element should be replaced in time; <br>pressure gauge: if the pointer fluctuates, check whether there is undrained water or gas in the system, and perform corresponding dehydration and exhaust; If there is oil or air leakage inside, replace with a new meter; <br>high-temperature oil pump: if there is vibration or abnormal sound, cavitation may occur, clean the oil filter debris; expansion tank: when abnormal sound or vibration occurs, check Whether there is blockage in the pipeline; <br>level gauge: if the display level is too low, add new oil in time: <br>temperature regulator: if the display shows that the temperature rises too fast, too slow or cannot be set, check whether the heating element is damaged or the system Whether the pipeline is blocked, and whether the components in the electric control cabinet are damaged. <br>Pipeline valve: Whether the switch position is correct and whether there is oil leakage. <br>9.2 The filter is set up mainly to prevent large solid particles in the pipeline from entering the high temperature oil pump. When installing, check the filter and do regular cleaning, which can greatly improve the service life of the heat transfer oil and the equipment. <br>9.3 During normal operation, the oil temperature in the expansion tank should not exceed 70°C. If the oil temperature is too high, it means that the system is not running smoothly or the pipeline is improperly connected. This is harmful to the service life of the heat transfer oil. The fault should be eliminated as soon as possible before putting it into operation. produce. <br>9.4 Frequent inspection and tightening of the heating body should be carried out.

9, thermal oil heater inspection and maintenance<br>9.1 Items for daily inspection<br>Heating body: if the terminals have overheating damage, check whether the electrical components are damaged, according to the extent of damage to decide to replace or repair, check the electrical components at the seal and seal and pipe plate french welds, if there is oil seepage phenomenon, to replace the electric heating element in a timely manner;<br>Pressure gauge: if the needle fluctuates, check the system for unresolfed water or gas, and carry out the corresponding dehydration exhaust; If there is oil leakage or gas leakage in the table, a new table should be replaced;<br>High temperature oil pump: if vibration or abnormal sound, this may occur cavitation, to remove oil filter debris; Expansion tank: When abnormal sound or vibration occurs, the line should be checked for blockage;<br>Level meter: If the level is too low, replenish the new oil in time:<br>Temperature regulator: If the display heats up too fast, too slowly or cannot be set phenomenon, check whether the electric heating element is damaged, whether the system lines are blocked, whether the components in the electronic control cabinet are damaged.<br>Line valve: the switch position is correct, there is no oil leakage phenomenon.<br>9.2 set the filter is mainly to prevent the pipe in the larger solid particles into the high temperature oil pump, in the installation should pay attention to check the filter and do regular cleaning, which can greatly improve the life of thermal oil and equipment.<br>9.3 During normal operation, the oil temperature in the expansion tank should not exceed 70 degrees C, such as the oil temperature is too high, indicating that the system is not running well or the pipeline is improperly connected, which is harmful to the service life of thermal oil, to troubleshoot as soon as possible, and then put into production.<br>9.4 The part of the heating body should be checked and tightened frequently.

9. Inspection and maintenance of heat transfer oil heater<br>9.1 items of daily inspection<br>Heating body: if the terminal has overheating damage, check whether the electric heating element is damaged, and change or repair according to the damage degree. Check the welding seam between the sealing part and sealing part of the heating element and the flange of the tube plate. If there is oil leakage, replace the electric heating element in time;<br>Pressure gauge: if the pointer fluctuates, check whether there is any water or gas not discharged in the system, and conduct corresponding dehydration and exhaust; if there is oil leakage or air leakage in the table, replace the new gauge;<br>High temperature oil pump: if there is vibration or abnormal sound, cavitation may occur, the oil filter debris shall be removed; expansion tank: in case of abnormal sound or vibration, check whether the pipeline is blocked;<br>Level gauge: if the liquid level is too low, add new oil in time:<br>Temperature regulator: if the temperature rise is too fast, too slow or cannot be set, check whether the heating element is damaged, whether the system pipeline is blocked or the components in the electric control cabinet are damaged.<br>Pipeline valve: whether the switch position is correct and whether there is oil leakage.<br>9.2 the filter is mainly set to prevent large solid particles in the pipeline from entering the high temperature oil pump. During installation, pay attention to check the filter and clean regularly, so as to greatly improve the service life of heat transfer oil and equipment.<br>9.3 during normal operation, the oil temperature in expansion tank shall not exceed 70 ° C. if the oil temperature is too high, it means that the system is not running smoothly or the pipeline is not connected improperly. This is harmful to the service life of heat transfer oil.
